Whats the difference between a straight, a flat and an I cylinder configurations?

do you know how to use google? I do.

flat - In 1896, Karl Benz was granted a patent for his design of the first boxer engine with horizontally-opposed pistons. His design created an engine in which the corresponding pistons reach top dead centre simultaneously, thus balancing each other with respect to momentum. Flat engines with four or fewer cylinders are most commonly boxer engines and are also known as, horizontally-opposed engines. This continues to be the design principle for high performance, automobile racing engines such as Porsches.

V - A V engine is a common configuration for an internal combustion engine. The pistons are aligned so that they appear to be in a V when viewed along the line of the crankshaft.

Inline - Usually found in 4- and 6-cylinder configurations, the straight engine (often designated inline engines) is an internal-combustion engine with all cylinders aligned in one row, with no or only minimal offset.
A straight engine is considerably easier to build than an otherwise equivalent horizontally opposed or V engine because the cylinder bank can be milled from a single metal casting and it requires fewer cylinder heads and camshafts. In-line engines are also much smaller in volume than designs like the radial, and can be mounted in any direction. Straight configurations are simpler than their V-shaped counterparts. Although six-cylinder engines are inherently balanced, the four-cylinder models are inherently off balance and rough, unlike 90 degree V fours and horizontally opposed 'boxer' 4 cylinders.

so a straight and an I are basically the same?

Straight and I are the same.

I'm waiting for a car to have in inline 12 ;)

gm used to make I-8's....thats pretty long.

Straight engines are always smoother than any other configuration right?

an inline 12 haha, they would have to place it diagonally.

Don't forget the radial engine.

Woo!!! Look at it go!!!

I4's are usually very rough unless it's completely balanced. I think the V configuration is the smoothest.

It is a car forum. What is wrong with asking a question about cars?

jag made an inline 12 that never went into production. it was built off of the XK E and that called it the XK EE. they obviously had to make the hood much longer. they had a camera on the front end.

i do remember jay leno owning a car with an inline 12. its an old school WWI era car.

nah i remember the tank car though. this one was a straight 12. not a v. its was a massively long engine. im not sure it was such a famous car of his. i think i may have seen it on my classic car or something like that

I can't think of any car out there with an I-12, not sure what has an I-12 that could be used in a car either.

Subaru boxer 4 FTW

Ferrari boxer 12 FTW.

Used in 365 GT4 BB, 512BB, BBi Testarossa/512TR/F512M.

Ferrari also used them in F1 in the 70's and i believe Mercedes tried one too.

And try this for size.

I'll let you ponder that one. :p

That is also a Subaru engine and was planned and i think used (prototype) as a Boxer 12 for the Koenigsegg in the mid 90's, no idea why the plan didn't advance. The engine used in power boats too. The Koenigsegg looked like this then in the 90's.
